In this post we are going to referring to a project that involves computer graphics related to an internal combustion (IC) engine in particular petrol engine.We are going to focus on the design of engine components, simulations of the engine cycle and will going to show visualizations of how the internal combustion (IC) engine works.
An internal combustion engine (IC Engine) is a type of heat engine that generates power by burning (using oxidizer usually air) fuel (typically gasoline(petrol), diesel, or natural gas etc) inside a combustion chamber. IC engines are used in many vehicles, including cars, motorcycles, trucks, and airplanes. Below is Figure of an Typical IC engine.
The cycle repeats continuously, with pistons moving up and down, creating the power needed to drive a vehicle or perform work. There are two common types of internal combustion engines:
